PulseAudio Buffer Size Tests. March 7, 2011 kurtrtaylor. It has been a few weeks, but in my defense, I have been pretty busy testing and debugging in this new environment. As an assignee to the Linaro project, my first task was to figure out if increasing the buffer size would enable the ARM cpu to drop into a lower power state.

uint32_t pa_buffer_attr::prebuf. Playback only: pre-buffering. The server does not start with playback before at least prebuf bytes are available in the buffer. It is recommended to set this to (uint32_t) -1, which will initialize this to the same value as tlength, whatever that may be. Initialize to 0 to enable manual start/stop control of the ...

PulseAudio manages all input and output streams of all desktop applications, providing them such features as clocking, buffering, and rewinding. Time management PulseAudio implements a per-device timer-based scheduler that provides clocking in the sound card domain, maintains optimal latency, and reduces the probability of playback glitches.
PulseAudio: Audio Streams - freedesktop.org
https://freedesktop.org/software/pulseaudio/doxygen/streams.html
In case of a buffer underrun the read index is equal or larger than the write index. Unless the prebuf value is 0, PulseAudio will temporarily pause playback in such a case, and wait until the buffer is filled up to prebuf bytes again. If prebuf is 0, the read index may be larger than the write index, in which case silence is played.
